Domain Name System (DNS) servers are crucial in translating domain names into IP addresses, allowing your computer or device to access websites and online resources. Knowing what DNS server is being used in your device can help troubleshoot network issues, improve performance, or enhance security. This guide will walk you through various methods to determine what DNS server is being used on different operating systems and devices.
What is DNS server?
A DNS (Domain Name System) server is a network service that translates human-readable domain names, like example.com
, into IP addresses, like 192.0.2.1
, which computers use to identify each other on the internet. It acts as a phonebook for the web, allowing users to access websites using easy-to-remember names instead of numerical IP addresses.
Methods to determine what DNS server is being used
There are several different methods used to determine what DNS server is being used
1. Windows
Using Command Prompt
- Open Command Prompt:
- Press the Windows Key + R to open the Run dialog box..
- Type cmd and press Enter.
- Run the Command:
- Type ipconfig /all and press Enter.
- Look for the “DNS Servers” line under your active network connection. It will show the IP addresses of the DNS servers in use.
Using Windows Settings
- Open Network & Internet Settings:
- Click the Start menu and choose Settings (gear icon).
- Go to Network & Internet.
- View Adapter Properties:
- Select Status and click on Change adapter options.
- Right-click on your active network connection (Ethernet or Wi-Fi) and select Properties.
- Choose Internet Protocol Version 4 (TCP/IPv4) and click on Properties.
- Here, you can view the DNS server addresses if they are manually configured.
2. macOS
Using System Preferences
- Open System Preferences:
- Click on the Apple menu and select System Preferences.
- Access Network Settings:
- Click on Network.
- View DNS Servers:
- Choose your active network connection (Wi-Fi or Ethernet) from the list on the left.
- Click Advanced, then go to the DNS tab.
- Here, you’ll find the list of DNS servers your Mac is using.
Using Terminal
- Open Terminal:
- Go to Applications > Utilities > Terminal.
- Run the Command:
- Type scutil –dns and press Enter.
- Look for the section labeled resolver #, which lists the DNS server addresses.
3. Linux
Using Command Line
- Open Terminal:
- Access the Terminal application from your Linux distribution.
- Run the Command:
- Type nmcli dev show and press Enter. Look for the section labeled IP4.DNS, which displays the DNS servers.
Alternatively, you can check the /etc/resolv.conf file:
- Type cat /etc/resolv.conf and press Enter.
- This file contains the DNS server addresses used by your Linux system.
4. iOS
Using Settings
- Open Settings:
- Open the Settings app on your iOS device.
- Access Wi-Fi Settings:
- Tap Wi-Fi and tap the information icon (i) next to your connected Wi-Fi network.
- View DNS Servers:
- Scroll down to the DNS section. You will see the DNS server addresses listed there.
5. Android
Using Settings
- Open Settings:
- Open the Settings app on your Android device.
- Access Network Settings:
- Go to Network & Internet (or Connections, depending on your device).
- Tap on Wi-Fi and then on your connected Wi-Fi network.
- View DNS Servers:
- Look for the Advanced section or similar. It will list the DNS server addresses being used.
Using Terminal (Rooted Devices)
- Open Terminal:
- If you have a rooted Android device, open a terminal emulator app.
- Run the Command:
- Type getprop net.dns1 and press Enter. This will display the primary DNS server.
- To check secondary DNS, use getprop net.dns2.
6. Router Settings
If you want to check the DNS server settings for your entire network, you need to access your router’s configuration:
- Launch a web browser:
- Enter your router’s IP address into the address bar (commonly 192.168.1.1, 192.168.0.1, or 10.0.0.1).
- Log In to Router:
- Enter the router’s username and password. If you still need to change these, they are often set to defaults like admin/admin or admin/password.
- Access DNS Settings:
- Navigate to the network settings or DNS configuration section. The location and name of this section vary by router brand and model.
- View DNS Servers:
- You will see the DNS server addresses configured for your network.
7. HostBet Integration
If you’re using services like HostBet, you might also need to consider how DNS settings are configured to optimize performance and security. HostBet, known for its reliable hosting solutions, can offer additional insights into how to best manage DNS settings for your specific needs.
Why Should I Regularly Check My DNS Server?
Regularly checking your DNS server is like giving your internet connection a routine check-up. Just as you wouldn’t drive a car without maintaining it, you shouldn’t rely on a DNS server without ensuring it’s performing optimally.
By keeping an eye on your DNS settings, you can catch and resolve issues that might be slowing down your browsing speed or compromising your online security. It also allows you to spot any unauthorized changes, which could be a sign of a security breach. In short, regular DNS checks help ensure that your online experience remains fast, secure, and trouble-free.
How Do I Change My DNS Server?
Your Internet Service Provider (ISP) generally determines your device’s DNS server. However, you can change your DNS server in a few ways:
- Use a VPN: Connecting through a VPN allows you to use the VPN’s DNS servers, which often come with robust privacy features to prevent DNS leaks.
- Modify Network Settings: You can adjust DNS server settings directly in your device’s network configuration.
- Update Router Settings: Changing the DNS settings on your home or office router will affect all devices connected to that network.
DNS queries play a crucial role in the functioning of the internet, but DNS servers can also log them, potentially exposing your browsing activity.
Conclusion:
Understanding and managing your DNS server settings is crucial for ensuring a reliable and secure network connection. Using the methods outlined in this guide, you can quickly determine what DNS server is being used in devices, make informed decisions about changing DNS servers, and troubleshoot network issues effectively. Whether you are a casual user or an IT professional, knowing how to access and interpret DNS server information is valuable for optimizing your online experience.
